Title: Method of fine working
Inventor: KUDO KAZUHIRO
IPC: H01L21/3065
Filed: 1985-12-16
Abstract: PURPOSE:To manufacture a sub-micron pattern, with superior yield and high precision, on a crystal thin film situated on a part deep from a surface of a multi-layered film, by using methods of anisotropic etching and selective etching on the multi-layered film comprising crystal thin films. CONSTITUTION:After a resist pattern layer 5 is formed on an upper Al0.4Ga0.6As layer by an ordinary photo-lithographic method, mesa-etching of the upper Al0.4Ga0.6As layer 1 is performed by using hydrofluoric acid group-etching liquid in which an etching speed of AlGaAs against a GaAs layer 2 becomes large. Namely, when etching of a crystal film is performed by the ordinary photo-lithography and a chemical etching method, a mesa-etching shape is obtained by selecting a crystal azimuth. When the etching attains to a layer different in composition, speed and shape in etching largely change. Then, pattern width d1 is formed on the upper layer, however, a window of d2 in width is formed on the lower layer, with the relation between film thickness h of the upper layer and the pattern width d1.

Filed: 1992-09-28
Abstract: PURPOSE:To perform the image synthesis of a three-dimensional object as the combination image of plural polygons in an excellent condition, without generating a clearance caused by an arithmetic error between adjacent polygons. CONSTITUTION:An image information supply source 10 performs a perspective projection transformation of a three-dimensional display object expressed as a polyhedron composed of the combinations of plural apex coordinates on a prescribed plane of projection and transforms the object to a two-dimensional image with plural polygons expressed by each projected apex combined. A field processor circuit 12 direct the X-coordinate of a contour point where the contour line connecting each apex of the polygons and a horizontal scanning line for raster display crosses to either one of the increase or decrease of the Y-axis crossing with the horizontal scanning line, calculates the X-coordinate while chaning the Y-coordinates of all the contours and calculates the left and right contour points pair of each polygon crossing with the horizontal line. An image synthesis circuit 14 combines plural polygons and outputs an image signal for two-dimensional image synthesis based on the left and right contour points pair of each polygon to be calculated. Thus, the three-dimensional object can be synthesized as a two-dimensional image without generating a clearance between adjacent combined polygons.

Title: Image pickup device and method
Inventor: OKADA KAZUHIRO
IPC: G03B9/02
Filed: 1998-10-07
Abstract: PROBLEM TO BE SOLVED: To prevent smear from occurring when a solid-state image pickup element is used. SOLUTION: When a photographer presses a shutter button, a CPU 14 outputs a signal for switching a mode from an E-to-E mode to a photographing mode. The operation of a CCD(charge-coupled device) 2 and a camera signal processing part 4 is switched from line thinning operation to all pixel reading-out operation. The operation state of an iris is switched from an automatic iris mode to a forced close mode and shifted to a close state. Thus, incident light on the CCD 2 is interceptred while the CCD2 performs all pixel reading-out operation. When the CPU 14 outputs a signal for switching the mode from the photographing mode to the EtoE mode, the CCD 2 and the processing part 4 are switched from the photographing mode to the E-to-E mode, and the iris is restored to a position where the iris exists just before the shutter button is pressed.
